A highly selective, IBX-promoted reaction has been developed for the oxidative cleavage of inertC(aryl)–N bonds on secondary amides while leaving the C(carbonyl)–N bond unchanged. This metal-free reaction proceeds under mild conditions (HFIP/H2O, 25 °C), providing facile access to various useful primary amides, some of which would be otherwise unattainable using conventional aminolysis and hydrolysis
已经开发出一种高度选择性的IBX促进的反应,用于氧化裂解仲酰胺上的惰性C(芳基)-N键,同时保持C(羰基)-N键不变。这种无金属的反应在温和的条件下(HFIP / H 2 O,25°C)进行,可以轻松获得各种有用的伯酰胺,而使用常规的氨解和水解方法则无法实现其中的某些。

N-unsubstituted β-ketoamides, hardly obtainable or non-accessible by non-enzymatic methods, have been synthesized, with good to excellent yields, by the generally fast hydration of the corresponding β-ketonitriles, catalysed by the bacterium Rhodococcus rhodochrous IFO 15564. This bacterium shows nitrile hydratase and amidase activities, the latter being inhibited during its growth phase with diethyl phosphoramidate
